Abstract: Un système de traitement des requêtes qui possède un gestionnaire de données et un gestionnaire de requêtes qui comprend un tampon. Le gestionnaire de requêtes appelle le gestionnaire de données pour accéder aux données en fonction d'une requête. Lorsqu'aucune vérification prédicative ou opération de consommation n'est effectuée sur l'enregistrement qui est accédé, le gestionnaire de données retournera de manière hypothétique l'enregistrement au gestionnaire de requêtes. Cependant, le gestionnaire de données effectue ce retour en écrivant les parties pertinentes de l'enregistrement dans un tampon. Le gestionnaire de données maintient la stabilisation de la page qui contient l'enregistrement pendant que le gestionnaire de données écrit dans le tampon. Le gestionnaire de données continue d'accéder aux enregistrements sur la page stabilisée et écrit ces enregistrements dans le tampon lorsque c'est approprié. Le gestionnaire de requêtes récupère les enregistrements dans le tampon après que le tampon a complété l'opération qui résulte de l'appel du gestionnaire de requêtes.

Abstract: An illuminated sign comprises a photoconductive plate and a series of light-emitting diodes of a type having a viewing angle of approximately 8° Being made from polycarbonate in a single piece, the photoconductive plate is inset from its back face, toward its front face but not through it, so as to define a series of indicia, each having a boundary. Each light-emitting diode is pressed into a recess opening at an outer periphery of the photo-conductive plate, between the front and back faces.      The recess orient the light-emitting diodes so that a part of the boundary of each of the indicia is disposed within the viewing angle of at least one of the light-emitting diodes and so that another part thereof is not disposed within the viewing angle of any of the light-emitting diodes. An opaque material covers the back face of the photoconductive plate, at least where the back face is visible through the front face thereof, except where the photoconductive plate is inset so as to define the indicia. A fluorescent material covers the indicia and is adapted to fluoresce at a color matching the color of light emitted by the light-emitting diodes when energized.

Abstract: A process for rapidly forming a ceramic shell mold on an expendable pattern (1) is disclosed. The process entails use of refractory slurries which include a large particle size colloidal silica sol binder. The colloidal silica sol binder has an average particle size of about 40 manometers, i.e., about 3-4 times larger than colloidal silica sol binders heretofore employed in manufacture of ceramic shell molds. The use of the large particle sols yields unfired ceramic shell molds (20) which have about 40 % to about 70 % greater unfired strengths compared to ceramic shells made with prior art small particle size silica sols. Prime coats and refractory back-up coats which use the large particle size sol dry about 30 % to about 40 % faster than prime coats and back-up coats which employ the smaller particle size silica sole of the prior art.

Abstract: The braking control system provides dual redundant control of hydraulically operated wheel braking for an aircraft. A primary hydraulic system (38) provides hydraulic power for normal operation of the plurality of wheel brakes, and a secondary hydraulic system (40) provides hydraulic power for alternate operation of the plurality of wheel brakes. A control unit is provided for controlling brake pressure communicated to the wheel brakes through the primary and secondary hydraulic systems, and a monitor channel is operatively connected to the primary hydraulic system for detecting faults in the primary and secondary hydraulic systems and for selecting between the primary and secondary hydraulic systems for providing braking pressure. The monitor channel detects occurrence of loss of pressure in the primary hydraulic system, if any brake has unwanted pressure applied, and if a fault is detected on the primary or secondary channels that affects more than one wheel brake on each landing gear. The primary hydraulic system comprises at least one primary hydraulic fluid control channel and at least one secondary hydraulic fluid control channel, the primary and secondary fluid channels being redundant and partitioned among the plurality of wheel brakes so that even if both the primary and secondary channels fail to apply pressure, braking will be lost to only a portion of the wheel brakes and the loss will be in a symmetrical pattern, and the secondary hydraulic system comprises at least one primary hydraulic fluid control channel and at least one secondary hydraulic fluid control channel.

Abstract: The present invention is a stent that is designed to have optimal strength a nd radio-opacity with good biocompatibility. To achieve optimal radio-opacity, the stent design of the present invention is adjusted to the specific radio-opacity and strength characteristics of the metal from which the stent is fabricated.

The achievement of optimal radio-opacity occurs in a stent that ideally is only 0.004 inches wall thickness or less. Such a stent would have a pre-deployment outer diameter (profile) that would be at least 0.003 inches less than currently marketed stents. Ideally, the sten described herein would have a wall thickness between 0.0025 inches and 0.004 inches.
